Chapter 6. Virtual Machine Performance and Resource Allocation

This chapter explores different settings that may improve a virtual machine's resource allocation and performance, if needed. These resource allocation settings affect the amount of resources given to a virtual machine and how virtual machines compete when in contention. These settings include shares, limits, and reservations and can be applied to CPU and memory resources. Shares and limits may also be configured for storage and network resource access, depending on your vSphere licensing tier.

In this chapter, you will learn about:

• CPU scheduler

• Memory reclamation techniques

• Shares, limits, and reservations

• Resource pools

• Network I/O Control

• Storage I/O Control

• Disk alignment

• Performance tuning
